In order that the technical features and practical effects of the present invention can be deeply understood and implemented according to the content of the invention, the preferred embodiments illustrated in the drawings are described in detail as follows.

1, 3 and 5 show a laptop charger according to a preferred embodiment of the present invention. According to these drawings, the charger comprises a main body 10, a charging cable 20, Including a stop plate 30, a transformer module 40 and an input port 50, the charging cable 20 is connected to the body portion 10 and can be housed in the body portion 10, the stop plate 30 is attached to the body portion 10. The transformer module 40 is detachably attached to the unit 10 and can be fixed so that the charging cable 20 does not drop off from the main unit 10. The transformer module 40 converts the input AC power into DC power and reduces the voltage. and the input port 50 is for connecting with an external power cord.

As shown in FIGS. 2-4, the body portion 10 includes a storage recess 11 and a winding portion 12. More specifically, as shown in FIGS. The receiving recess 11 is recessed into the lower surface 17 of the body portion 10 as shown in FIG. 2 and the winding portion as shown in FIG. 12 is formed so as to protrude from the bottom of the storage recess 11 . As shown in FIG. 4, the charging cable 20 has one end connected to the main body 10 and the other end having a charging connector 21 that can be connected to a notebook computer. The cable 20 is electrically connected to the transformer module 40 and the transformer module 40 is electrically connected to the input port 50 . As shown in FIG. 6, the power cord has a power supply connector 51 connectable to the input port 50 at one end and an outlet plug (not shown) at the other end, and an external AC power source is supplied from the power cord. The power is supplied to the transformer module 40 through the input port 50, converted into step-down and DC power, and then supplied to the laptop computer through the charging cable 20 for charging.

Furthermore, as shown in FIG. 3 , the charging cable 20 can be wound around the winding portion 12 and completely housed in the housing recess 11 . In addition, as shown in FIGS. 2 and 3, the stop plate 30 can be coupled to the winding portion 12 and prevents the charging cable 20 stored in the storage recess 11 from coming off. Specifically, when the charging cable 20 is in the stored state, it is spirally wound around the winding portion 12, and when using it, the stop plate 30 is temporarily removed and the required length is adjusted. After pulling out the charging cable 20, the stopper plate 30 is attached again, and the charging connector 21 of the charging cable 20 is inserted into the charging port of the notebook computer.

After the required length of the charging cable 20 is pulled out and connected to the laptop computer, the stop plate 30 is restricted so that the extra portion of the charging cable 20 stored in the storage recess 11 is not pulled out. This prevents the charging cable 20 from being too long and hanging down on the ground or being disturbed, and prevents people from accidentally tripping and falling, disconnecting the charging connector 21, or cutting the charging cable 20. It can prevent the notebook computer connected to the power supply from being pulled and falling to the ground.

As described above, the laptop computer charger according to the present invention is provided with the storage recess 11, the winding portion 12, and the stop plate 30, so that the charging cable 20 can be wound around the winding portion 12 and stored in the storage recess 11 when being carried. By storing it inside and fixing and protecting it with the stop plate 30, it is possible to improve the convenience of carrying it, so that the charging cable of the existing laptop computer charger is very long and can be carried around. At the same time, it eliminates the problem of being difficult to store due to the transformer itself or other things getting tangled in the bag, while at the same time prolonging the service life by properly protecting the charging cable, By allowing the extra portion of the charging cable 20 to be stored, the safety during use can be enhanced.
